My laptop recently lost it's ability to connect to my printer over the network. Greg came and worked on it for 2-1/2 hours in my home, concluded it was a glitch in the printer software, and took it to the shop to clean things up. He brought it back the next day and I'm able to print wirelessly again. Greg is a real wizard, and I know he spent more time on this than I was billed for. Thank you Greg for your excellent service!
